Application filed August 2, 1890.

same, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification. a;

My invention relates to a combined cotton chopper and cultivator, theobject of the same being toprovide a machine that will cultivate theplants, clean the weeds from between the rows of plants, throwfresh-dirt up around the same, and thin them out, bringing the plants toa stanc This machine may be used to cultivate and thin out any plantsplanted in drills or rows and requiring to be brought to a stand.

\Vith these ends in view my invention consists in the parts andcombination of parts, as will be fully described, and pointed out in theclaims.

In the accompanying drawings, Figure 1 is a perspective view of mymachine. Fig.2 is a longitudinal vertical central section through thesame. Fig. 3 is a detail perspective View showing the spring-catch leverlocated on the axle. Fig. at is a perspective view of the notched headof the cultivator-beams. Fig. 5 is a perspective view of the clip towhich the thinneror chopping arm is pivoted. Fig. 6 is asimilar view ofthe chopping-blade provided with a slot. Fig. 7 is a perspective view ofaslight modification of means for pivoting the chopper-arm to thecultivator-beams.

A represents the axle of the machine, and a a the wh eels on which themachine runs. The wheel a is provided with a ring having cams on itsouter surface. a and a are hangers suitably secured to axle A, on whichare pivoted the cultivator-beams B and B by means of the plate aThelower ends of these beams are secured together by means of a plate BSecured to the beams B and B, respectively, are shovels b b and cuttersb b. The upper ends of said beams are secured together by Serial No.360,762. (No model.)

means of a slotted or notched plate N, which engages With a lever c,which is pivoted in plates 0 O and works between guides secured to theaxle. This lever c is provided with a notch c and a lug or projection 0said lug serving to limit, when desired, the upward movement of thebeams B and B.

c is asuitable spring secured to the axle and presses against the curvedlever or arm 0. is a suitable handle secured to lever or arm 0.

D is the chopper-arm, which is pivoted to the cultivator-beams by meansof the plate (I. Secured to the lower end of the arm D by means of screwor bolt (1 is an adjustable chopping-blade D, having an elongated slot 4C1 The upper end of the arm D is angular and bounded or faced with metalor other suitable material (1. Said plate (Z is provided with a lug orprojection (1 which engages a right-angle plate cl, secured to the axle.

(Z is a flat orother spring, which is secured to hanger a and engagesthe chopper-arm D.

d is a ring secured in the said arm.

E is a guide secured to the beam B, having a depending end 6, said guideserving to limit the upward and outward motion of the chopper-arm.

I) is a handle or lever secured to the beam BI The operation is asfollows: The machine being in operative position, as shown in Fig.

1, it is placed at the beginning of a row and started forward, theangular end of the chopping-arm engagingthecam-ringa Theknives I) outthe row out from the sides of the plants, and the chopper-blade D cutsthe weeds, &c., from between the plants designed for the hill or stand.The shovels h, following, throw the soil up around the plants. It willbe seen that the row will be chopped to a stand and dirted on both sidesat a single passage of the machine along said row. here it. is desiredto throw the beams 13 and B out of a directline with the wheels at anda, the lever o is drawn forward by means of the handle 0 the driver thenthrows the beams to either side by means of lever b, and the lever c isthen let go and it engages one of the side notches in the.

notched plate 19 The chopper-arm, when it is desired, is thrown out ofengagement with the cams on wheel a by placing the pro- ICC jection (lin engagement with d. In moving the machine from one place to another itis always desirable to raise the shovels and blades from contact withthe ground. To effect this raising I simply pull the lever 0 forwarduntil it is out of engagement with the notched plate b and force thebeams down by means of lever 1) until the notched plate 11 comes intoengagement with the notch c in lever c.

WVhat I claim, and desire to secure by Letters Patent, is.-

1. A cotton-cultivator consisting of the beams pivoted on suitablehangers secured to the axle, cutting-blades and shovels secured,respectively, to the beams, and a notched plate connecting the upperends of the beams, in combination with a notched lever secured to theaxle and lever 17, all constructed and operating substantially asdescribed.

2. In combination with a cultivator, substantially as herein shown, aring composed of a series of cams secured to the inside of one of thewheels of the cultivator, a chopperarm D, pivoted to said cultivator andengaging said cam-ring, the adjustable choppingblade, and the spring (Zand catch (1 all combined and operating substantially as described.

3. The combination, with a cultivator having beams 13 and B, of anotched plate 39 securing said beams together, and a curved lever 0,pivoted, as described, and provided with notches and a lug, spring 0",and guideways 0 all substantially as described.

I. A combined cotton chopper and cultivator, consisting of the beams Band B, pivotally secured by meams of plate a 0n hangers and providedwith cutting-blades b b and shovels b b and a notched plate W, a curvedlever or arm 0, provided with notches and a projection, said lever orarm working in guideways 0 and engaging the notched plate 19 spring 0,chopper-arm pivoted to the beam 13 and provided with an adjustablechoppingblade D at one end, and an angular portion at the other end anda lug cZ a catch (1 and a cam-ring which is engaged by and operates thechopper-arm, spring (1 and guide E, all constructed and operatingsubstantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
